Some parents have been known to give their kids really odd names. We hear about this mostly in the celebrity world; e.g. Kim Kardashian and Kanye West naming their daughter North (so she’ll be “North West”). There are, however, countless other stupid child names given to much-less-famous people, including some so bad that they end up becoming famous for them (e.g. neo-Nazi Heath Campbell naming his son Adolf Hitler).

I can think of lots of people who would disagree with Ballew, including (and perhaps especially) Jews, who some two and a half millennia ago invented the notion and title of “messiah” and who think no one, not even Jesus Christ, has yet earned that moniker. (I admit it’s possible they might be offended by naming a child “Messiah,” but for their own reasons. But I don’t know that for sure.)

I don’t think it’s wise to name a child “Messiah,” myself, mostly because so many other people in his life are going to get their knickers in knots over it — just as Ballew clearly did. Which, of course, would only be the result of their own irrational metaphysics; but it’s still not something a boy ought to pay the price for, his whole life.

Note: See two salientcomments below for clarification of Jewish views of the Messiah and on people with that name. It turns out my half-hearted conjecture was incorrect. My thanks to both commenters.

Actually, the ancient Hebrews, who invented the term "messiah", didn't reserve the title for just one person. For example, they regarded Cyrus the Great, king of Persia, as a messiah.
Personally, I think it's tragic that anyone would name their kid "Lu Ann", but that's my personal opinion, and I don't believe we should force the Judge to change her name.
